Stove



UNITED srarns rarnsr amas CHARLES R. WHEELER, OF BOSTON, MASSACHUSETTS.

Specification of Letters Patent- No. 11693", dated July 18', 1840.

To all whom it may concern Be it knownthatI, CHARLES R. WHEELER,

grates of ordrnary constructlon and as seen in the drawings.

of Boston, in the county of- Suffolk and State of h I'assachusetts, have invented a new and useful Improvement in Parlor-Grates placed, the bars of which are arranged in ,t-hje usual manner. place is beveled inward toward the top as seen' in Figs. 1, 2, and 3 so' that the smoke ;&o'. shalleonverge to and pass through the or Open Fireplaces.

The sad improvement, the principlesthereof and modes in Which I have co-ntem-' plated the application of the same by whichit may be distinguished from other inven-' tions of a like character,together with such parts or combinations I claim as my invention and consider original and new I have herein set forth and described, which description taken in connection with the accompanying drawings herein referred to, forms my specification.

It is well known that the great desicleratum in grates or stoves, is to heat the atmosphere in the room to the requisite temperature, for comfort, with the least possible eX- penditure of coal or other fuel. It will likewise be admitted that this object will be more effectually attained by revolving the air in the room, and, as it were, constantly recharging the same with caloric. This principle has already been adopted in the construction of stoves but has not, to my knowledge been applied to the open grate or fireplace, which application or combination constitutes the novelty or distinguishing feature of my improvement, by which,

besides heating the air of the room by the smoke &c. I obtain the heat directly from the fuel, and not through the medium of a conducting material, as must necessarily be the case in stoves, where the fuel is inclosed on all sides.

The figures of the accompanying plate of drawings represent my improvements.

Figure 1, is a front View or elevation of my-parlor grate; Fig. 2, represents a detailed top View, or plan showing the appearance of the interior parts of the grate, when the top is removed; Fig. 3, is a longitudinal sect-ion taken vertically on the line A B; Fig. 4:, being a transverse section taken vertically on the line C D.

a-a aa, &c., Fig. 1, is the casing or exterior of the grate which incloses the various chambers or apartments.

6 Z), Fig. 3, is the ash box and c c the movable hearth, shaped and arranged as, in

is the fire-place inwhichthe fuel is The ack F of this fire from the top to the bottom of the grate asseen in Fig. 4,) are similarly, and respectively arranged, with cylinders g, g, and partitions h h, h h, &c., situated or fixed in the same as seen in the drawings, dividing the spaces 6 e f f f f c e ce c f f f f e e 6 each into two apartments 6 6 06-0, ffff f, e e e c e, f 7 f f,.which communicate with each other by means of openings h, it, in the bottoms of the partitions h h h h, Fig. 4: thereby forming two descending fines e e e, &c. and e c e, &c. and two ascending ones f f 7, &c. and f f f, &.c. In the sides 2' i, 2' 2" Figs. 2, 3 of the ascending flues, spaces or apertures 7s, 70, 7c, &c., are formed, which open into the Wedge shaped flue Z Z at the back of the fire place, which latter flue communicates with the discharge pipe at in the back of the grate.

The cylinders g, 9, receive the atmosphere of the room through circular openings 7, n,

"at their bottoms, and the smoke passing through the various fiues in the directions indicated by the arrows in the different drawings, viz. through the flue G G into the chamber cl (Z (Z (Z; thence to the right and left down the descending fines c e e &c. e c e &c. passing through the openings h h in the partitions h h, h h and upward through the ascending firms 7 f f, &c. f f f &c. thence through the openings 74, lo, and flue Z, Z, to the discharge pipe m, and thus,

as will readily be perceived, heat every portion of the surface of said cylinders, with the exception of the two small portions at which they are tangents tothe partitions 72, 7t 71, i z", &c." Thus the air in the cylinders becomes heated, and isalloWed to escape into the room again, through any suitable 1 openings '0, Fig. l, in the top of the cylinders or grate.

When the room becomes sufficiently Warm, the smoke may be made to escape directly through the discharge pipe m, by

- means of the damper pmoved by the handle or Wire, 9, and sliding'on supports 7", r,

as seen in the drawing, said damper operating with the openings, .9 Fig'sJ3 and 45in thepartition t 6 so as to allow or prevent the smoke from passing into'the-fiuel land through the same into the discharge pipe m.

'The peculiar arrangement of the cylinders and partitions should 1 beparticularly noted, the same being suchthat th'e'smoke has a rotary motion, and Willheat every portion of the surface of the cylinders. The

fireplace will be lined with fire brick, soapstone or other suitable material, and the exterior of the grate may be formed of sheetor cast iron, or a combination of both materials according to. the pleasure of the manufacturer. y i

Having thusdescrib'ed my improvements in parlor grates, I claim in the same as follows g Constructing the hollow jambs-by making each ofthem with a vertical division plate,

In testimony that the above is a true description of my said invention and improvement I havefhereto set my signature this eighth day'of February in the year of our Lord eighteen hundredand forty.

so as to conduct the smoke down on one side :and up on the'other; in combination With the cylinders, placedbetween said flues, for the purpose of heatingthe air of the room; the Whole being constructed arranged and operating inthe'manner and for the puri poses herein above described.
